Travel without the roaming bill. eFlexSim gives your phone mobile data the moment you land. Choose a plan, pay, and install — it takes about a minute, and there is no physical SIM to swap, lose, or queue for. WHERE IT WORKS Data plans for 204 countries and 10 regional bundles, plus global plans that follow you across borders on a single eSIM. Plan lengths run from a few days to a full year, so a weekend city break and a six-month posting are both covered. HOW IT WORKS 1. Pick your destination and a plan that fits the trip. 2. Pay in the app. 3. Install the eSIM — a QR code or a single tap, depending on your phone. 4. Land, switch it on, and you are online. Your normal number stays exactly where it is. The eSIM carries data only, so calls and messages on your usual line are untouched, and you can keep your home plan active alongside it. BUILT FOR ACTUAL TRIPS - Check compatibility before you buy — the app asks your phone directly whether it supports eSIM, rather than guessing from a list of model names. - Watch your usage. See how much data is left and how long the plan runs, without hunting through a carrier app. - Top up mid-trip. Extend a plan that is running low instead of starting over. - Get a low-data warning before you run out, at a threshold you choose. - Keep your plans offline. Installed eSIM details stay readable with no connection — which matters precisely when you have none. - Pay with a card or Apple Pay, and keep a wallet balance for the next trip. SUPPORT Real help from real people, in the app. If an install goes wrong we will tell you what actually happened and how to fix it. eSIM requires a compatible, carrier-unlocked device. eFlexSim checks this for you before you buy.
